Description

Technical Field

[0001] This invention relates to the field of electrostatic flocking equipment technology, specifically to an electrostatic flocking machine. Background Technology

[0002] Electrostatic flocking technology utilizes a high-voltage electrostatic field to orient short fiber flocking onto a substrate coated with adhesive. It is widely used in industries such as decoration, packaging, and toy manufacturing. Currently, traditional electrostatic flocking machines on the market typically employ an integrated design or a direct connection between the main unit and the nozzle. During operation, the operator must hold the nozzle that generates high-voltage static electricity and aim it at the adhesive-coated workpiece at a close distance (e.g., 3-5 cm) to perform the flocking. This operating mode has the following significant drawbacks: Inconvenient to operate and inefficient: Operators need to simultaneously hold the workpiece (especially small or irregularly shaped workpieces), control the distance and angle of the nozzle, and control the start and stop of the equipment. This requires high hand-eye coordination and physical strength, making it difficult to perform long-term, precise operations, resulting in low production efficiency.

[0003] Significant safety hazards exist: When the equipment is operating, the nozzles carry thousands of volts of high-voltage static electricity. Traditional operation requires operators to wear insulated shoes and gloves for protection, and the power must be turned off and manual discharge performed (such as by touching the nozzles to metal) before adding, changing, or stopping the machine. In actual production, these cumbersome procedures are easily overlooked, posing a risk of electric shock.

[0004] Harsh working environment: During the flocking process, free flock fibers that fail to adhere effectively to the workpiece will be scattered in the air, polluting the working environment, affecting the health of operators, and causing waste of raw materials.

[0005] Equipment grounding and discharge rely on manual intervention: Reliable grounding is a prerequisite for safe operation, but current technology lacks automatic monitoring of the grounding status. Furthermore, post-shutdown charge discharge depends entirely on manual operation, creating safety blind spots.

[0006] Therefore, there is an urgent need for an electrostatic flocking equipment and method that can solve the above problems and achieve a safer, more efficient and environmentally friendly solution. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide an electrostatic hair implantation machine to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides an electrostatic flocking machine, including a main unit, a flocking device, a flexible flocking tube, a foot switch, and an open operating box. The main unit contains a high-voltage generating module and a control module. The main unit's housing is equipped with a power interface, a grounding terminal, a high-voltage switch, and a high-voltage output interface. The flocking device is disposed inside the main unit and electrically connected to the high-voltage generating module. The flexible flocking tube has a first end connected to the inlet of the flocking device, and a second end forming a flocking outlet for ejecting flocking fibers. The foot switch is electrically connected to the control module and generates an on / off control signal. The open operating box is independently disposed beside the main unit and is used to accommodate the workpiece to be flocked. The flocking outlet of the flexible flocking tube extends into the operating box, and at least one side wall of the operating box is open to form an operating surface. The control module is configured to respond to the signal from the foot switch, controlling the high-voltage generating module to supply and de-energize the flocking device, thereby controlling the flocking fibers to be ejected from and stopped from the flocking outlet.

[0009] In addition, the electrostatic hair implantation machine proposed above according to this application may also have the following additional technical features: In one embodiment of this application, the housing of the host is further provided with a fuse holder and an external control interface; a fuse connected in series with the power interface is installed in the fuse holder; the foot switch is electrically connected to the external control interface via a control line.

[0010] In one embodiment of this application, a safety control unit is further included. The safety control unit is electrically connected to the control module and includes at least one of a grounding detection circuit, a static electricity elimination circuit, and a charge discharge circuit. The grounding detection circuit is configured to detect the grounding status of the grounding terminal and prevent the high-voltage generating module from starting when the grounding is invalid. The static electricity elimination circuit is connected between the output terminal of the high-voltage generating module and the grounding terminal to eliminate induced static electricity. The charge discharge circuit is configured to automatically discharge residual charge on the flocking device and the flexible flocking tube when the foot switch is turned off.

[0011] In one embodiment of this application, the bottom of the host is fixedly provided with an anti-static foot pad that is in direct contact with the ground.

[0012] In one embodiment of this application, the flocking device is provided with a flocking cavity. When the flocking device is powered on and generates an electrostatic field, and the foot switch remains on but the flocking device is stationary, the electrostatic field can attract the free flocking fibers in the operating box that are not attached to the workpiece back into the flocking cavity.

[0013] In one embodiment of this application, a grounding conductive layer is laid at the bottom of the operating box, and the grounding conductive layer is electrically connected to the grounding terminal of the host.

[0014] In one embodiment of this application, the host is provided with a circuit board, and the high voltage generating module and the control module are disposed on the circuit board; the circuit board is integrated with multiple plug interfaces for connecting the cooling fan, the high voltage generator, the working indicator light, the power indicator light, the internal power circuit and the output terminals of the transformer.

[0015] The electrostatic flocking machine's flocking method includes the following steps: S1: Equipment preparation steps: reliably ground the host and fill the flocking machine with flocking fibers; S2: Workpiece placement step: Place the workpiece to be flocked into the operating box through the operating surface and position it above the flocking outlet. S3: Flocking operation steps: Step on the foot switch to power on the flocking machine to spray flocking, and at the same time hold and move the workpiece to make the surface to be flocked receive flocking. S4: Stop the removal step, release the foot switch to stop the flocking, and then remove the flocked workpiece.

[0016] In one embodiment of this application, in step S1, the fiber length of the flocking fibers is 0.6 mm to 0.8 mm; in step S3, the distance between the surface of the workpiece to be flocked and the flocking outlet is maintained at 3 cm to 5 cm, and the surface to be flocked is kept perpendicular to the flocking direction of the flocking outlet.

[0017] In one embodiment of this application, in step S1, if the flocked fibers are damp, they are subjected to a drying pretreatment before being loaded; the drying pretreatment includes sieving the fibers using a vibrating screen made of two layers of window screen.

[0018] The advantages of this invention compared to existing technologies are: (1) The high voltage start and stop are controlled by a foot switch, realizing the "hands away from high voltage" operation mode. The operator can focus on moving the workpiece with both hands without touching or operating the high voltage components at close range. Combined with safety units such as automatic discharge and grounding detection, the risk of electric shock is greatly reduced and the safe operation process is simplified.

[0019] (2) Using both hands to operate the workpiece allows for more flexible and stable control of the distance, angle and movement trajectory between the workpiece and the nozzle, which is conducive to achieving a uniform and dense flocking effect, and is especially suitable for fine operations on complex-shaped workpieces.

[0020] (3) The independent open operation box confines the flocking process to a limited space. Combined with the flocking machine's flocking recovery function (electrostatic adsorption), it effectively reduces the scattering of flocking in the workshop, protects the health of operators, and reduces raw material loss.

[0021] (4) The design of separating the main unit from the control box makes the equipment layout more flexible. The integrated plug interface design on the circuit board facilitates the identification, connection and maintenance of internal components.

[0022] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 9 As shown, an electrostatic flocking machine according to an embodiment of the present invention mainly includes a main unit 1, a flocking device 2, a flexible flocking tube 3, a foot switch 4, and an open operation box 5.

[0028] The main unit 1 is the central hub of the entire device, integrating a high-voltage generation module and a control module. It is responsible for providing the high-voltage electrostatic field required for flocking and receiving control signals. The main unit 1 has necessary external interfaces on its casing.

[0029] The flocking device 2 of this invention is fixedly installed inside the internal cavity of the main unit 1. The flocking device 2 has a flock cavity for accommodating the flocked fibers, and its core is a high-voltage electrode directly connected to the output terminal of the high-voltage generator module. When the high-voltage generator module is working, the high-voltage electrode establishes a strong electrostatic field within the flock cavity and at the outlet of the flocking device 2.

[0030] The flexible flocking tube 3 serves as a channel connecting the flocking machine 2 and the working area. Its first end (inlet end) is sealed to the flocking outlet of the flocking machine 2, and its second end (outlet end) forms the flocking outlet 31 for directional spraying of flocking fibers. The flexible flocking tube 3 is flexible, which makes it easy to adjust the final direction of the flocking outlet 31 within a limited space. However, it is usually fixed during operation and does not require the operator to move it by hand.

[0031] The foot switch 4 is the core human-machine interface component for realizing the "hands-off high voltage" operation mode in this invention. It is connected to the main unit 1 via a control line and is typically a normally open contact switch inside. When the operator steps on it, the switch contacts close, generating an on signal; when the operator releases the foot, the contacts open, generating an off signal. This signal is transmitted to the control module inside the main unit 1.

[0032] The open-type control box 5 is a box structure placed independently of the main unit 1. Its function is to provide a relatively enclosed and controllable operating space for flocking operations. At least one side wall of the control box 5 is completely open, forming the operating surface 51. The operator's hands can freely enter and exit the box through this operating surface 51 to pick up, place, and move workpieces. The flocking outlet 31 of the flexible flocking guide tube 3 extends into the internal space of the control box 5 from the top or side wall and is typically fixed to point towards the working area inside the box.

[0033] The workflow is briefly described as follows: Before operation, the workpiece is placed in the open control box 5. During operation, the operator's feet are outside the control box 5, and one foot controls the start and stop of the foot-operated switch 4; both hands are inserted into the control box 5 through the operating surface 51, holding the workpiece and moving it below the flocking outlet 31. When the foot is pressed on switch 4, the control module in the main unit 1 receives a signal and drives the high-voltage generator module to supply power to the flocking machine 2. A high-voltage electrostatic field is established, and the flocking fibers are ejected from the flocking cavity of the flocking machine 2 through the flexible flocking tube 3 and out of the flocking outlet 31 under the action of the electric field force, vertically shooting onto the surface of the workpiece to complete the flocking. Releasing the foot-operated switch 4 cuts off the high voltage and stops the flocking. Throughout the entire process, the operator's hands do not need to touch any live parts, nor do they need to operate the nozzle, greatly improving safety, ease of operation, and precision.

[0034] In one embodiment of this application, please refer to Figure 1 The casing of host 1 is typically made of insulating material, such as engineering plastic. Multiple functional interfaces are located on the casing: Power interface 11: Used to connect to 220V AC mains power to power the entire device.

[0035] Grounding terminal 12: This is a critical safety interface. It must be reliably connected to the building's ground using a conductor of sufficient cross-section to discharge any static electricity that may be induced in the casing and to provide a safe protective grounding.

[0036] High-voltage switch 13: This is a mechanical switch used to control the main power supply to the high-voltage circuit of the equipment. This switch should be turned off when the equipment is not in use for an extended period or before internal maintenance.

[0037] High voltage output interface 15: This interface is connected to the high voltage electrode of the flocking device 2 via an internal high voltage line, and is used to transmit the thousands of kilovolt DC high voltage generated by the high voltage generation module to the flocking device 2.

[0038] Fuse holder 16: Contains a fuse connected in series with the circuit of power interface 11. In the event of a short circuit or overload, the fuse blows to protect the internal circuitry and prevent further damage. When the equipment is not working, the fuse should be checked first.

[0039] External control interface 14: This is a multi-pin interface used to connect the control line of the foot switch 4. The control module receives the on / off status signal from the foot switch 4 through this interface.

[0040] Please see Figure 6 The main unit 1 contains a main circuit board 6. The high-voltage generation module and the control module, as core circuit units, are both located on this circuit board 6. This integrated design facilitates production and maintenance.

[0041] High voltage generator module: It is usually composed of an oscillation circuit, a high frequency transformer and a voltage multiplier rectifier circuit, etc. Its function is to convert the input 220V low voltage AC power into several kilovolt DC high voltage.

[0042] Control module: This can be implemented based on a simple relay logic circuit or a microcontroller. Its core function is to receive the electrical signal from the foot switch 4 and control a power switching device (such as a relay or solid-state relay) based on this signal, thereby controlling the on / off state of the input power supply to the high-voltage generator module. That is, pressing the foot connects the high-voltage power supply, and releasing the foot disconnects the high-voltage power supply.

[0043] Circuit board 6 also integrates multiple plug interfaces, which connect to other components of the equipment via internal wiring harnesses. These interfaces include, but are not limited to: interfaces for connecting cooling fans, interfaces for connecting the output terminals of each winding of the high-frequency transformer in the high-voltage generation module, interfaces for connecting working indicator lights (indicating whether the high voltage has started) and power indicator lights, and internal power circuit output interfaces for supplying power to various circuits. This plug-in design makes assembly, testing, and maintenance more convenient.

[0044] In a preferred embodiment, the control module may also be connected to a safety control unit. This safety control unit may be integrated on the circuit board 6 and may include one or more of the following circuits: 1. Grounding Detection Circuit: This circuit continuously monitors the loop resistance between grounding terminal 12 and the earth, or during power-on. If excessive grounding resistance is detected (i.e., poor grounding or no grounding), the circuit sends a fault signal to the control module. The control module will then prevent the high-voltage generator module from starting and issue an alarm via the human-machine interface (e.g., indicator lights or a buzzer). This enforces the safety procedure of "grounding before powering on" for the equipment.

[0045] 2. Charge Discharge Circuit: This circuit is connected between the high-voltage output terminal and the ground terminal, and consists of a discharge resistor and a controlled switch (such as a high-voltage relay) connected in series. When the control module detects that the foot switch 4 changes from the "on" to the "off" state, it immediately closes the controlled switch while cutting off the power supply to the high-voltage generating module. The discharge resistor quickly discharges the charge remaining on the high-voltage electrode of the flocking device 2, the flexible flocking tube 3, and even the attached flocking fibers to the ground. This process is automatic and instantaneous, requiring no manual discharge operation by the operator (such as touching metal with the nozzle), fundamentally eliminating the risk of electric shock due to forgetting to discharge.

[0046] 3. Static electricity elimination circuit: This can be a simple resistor or RC network connected in parallel at the high voltage output terminal to eliminate induced static electricity on the line and improve system stability.

[0047] In addition, to further enhance the electrostatic discharge capability of the main unit 1 casing, anti-static feet can be fixedly installed on the bottom of the main unit 1. These feet are usually made of conductive rubber material to ensure good conductive contact between the metal base plate or casing of the main unit 1 and the working surface covered with anti-static flooring, further eliminating induced static electricity in the casing.

[0048] In one embodiment of this application, the flocking device 2 is built into the cavity of the main unit 1. It has an openable cover at its upper part for holding the flocking fibers. The lower part of its fiber cavity is connected to the first end of the flexible flocking tube 3. When high voltage is applied to the electrodes inside the flocking device 2, the fibers in the fiber cavity become charged with the same type of charge due to induction. Under the influence of the strong electrostatic field generated by the high-voltage electrodes, they repel each other and move along the direction of the electric field, entering the flexible flocking tube 3.

[0049] The principle of automatic flocking recovery is as follows: When the foot switch 4 is pressed, a high-voltage electrostatic field is established. However, when the operator holds the workpiece still or leaves the work area, the flocking fibers ejected from the flocking outlet 31 will be suspended in the air in the open operating box 5 because there is no workpiece to catch them. At this time, the electric field strength is strongest at the entrance of the flocking chamber of the flocking unit 2 (where it connects to the flexible flocking tube 3). These suspended, charged free flocking fibers will be attracted in the opposite direction under the action of the electric field force and pulled back into the flocking chamber of the flocking unit 2 along the flexible flocking tube 3, thereby achieving automatic recovery, reducing material waste and environmental pollution, and making the recovery process automatic and efficient within the closed operating box 5.

[0050] The flexible guide tube 3 needs to be made of an insulating material that is not prone to static electricity buildup, and its length and flexibility need to meet the requirements of guiding the outlet 31 to a suitable working position in the operating box 5.

[0051] The foot switch 4 is a commercially available foot switch with a dustproof and waterproof housing. Its control wire is equipped with a plug that matches the external control interface 14 of the main unit 1, enabling quick connection.

[0052] In one embodiment of this application, the open operating box 5 is a physically isolated working space. Its top or side wall has an opening for fixing the flexible lint guide tube 3, through which the lint outlet 31 extends into the box. The open design of the operating surface 51 allows the operator to conveniently place, adjust, and remove workpieces, as if working in front of an open "window," while effectively limiting the spread of lint throughout the workshop.

[0053] In one optimized embodiment, a grounding conductive layer 52 is laid on the bottom of the operating box 5 (see [link]). Figure 3 The grounding conductive layer 52 can be made of a metal plate, a conductive rubber pad, or a conductive coating, and is reliably connected to the grounding terminal 12 of the host 1 via a wire. Its functions are threefold: first, to provide a defined zero-potential reference surface for workpieces (especially non-conductive workpieces) placed inside the operating box 5, which is beneficial for forming a stable flocking electric field; second, to help dissipate residual charge inside the box during flocking recovery; and third, to further enhance the safety of the operating area.

[0054] Operating instructions for an electrostatic hair implantation machine: Based on the above-mentioned electrostatic flocking machine, the present invention also provides a flocking method, which is safe and efficient, and specifically includes the following steps: Step S1: Equipment preparation steps.

[0055] First, the grounding terminal 12 of the main unit 1 must be reliably connected to the earth via a compliant grounding wire. This is the primary prerequisite for the safe operation of the equipment. Check the power connection of the main unit 1 to ensure that the high-voltage switch 13 is in the off position. Next, open the cover of the flocking machine 2 and fill its flocking chamber with a sufficient amount of flocking fibers that meet the specifications. The fiber length of the flocking fibers is preferably 0.6mm to 0.8mm, as this specification of flocking fibers has good flight characteristics and uprightness in an electrostatic field. If the purchased flocking fibers are slightly damp, it will affect their charging performance and flowability, and they need to be dried and pre-treated before loading. A simple and effective pre-treatment method is to use a simple vibrating screen made of two layers of ordinary window screen to vibrate and filter the flocking fibers. The vibrating and sieving process can filter out clumps and remove some moisture through airflow.

[0056] Step S2: Place the workpiece in the workpiece.

[0057] The operator places the workpiece to be flocked, which has been evenly coated with adhesive, into the operating surface 51 of the open operating box 5. The workpiece is placed on the bottom of the operating box 5 (or the workbench surface), and its position is adjusted so that the surface to be flocked is facing upwards, directly opposite and above the flocking outlet 31 of the flexible flocking tube 3. The operator's hands are inside the operating box 5, while the rest of their body is outside the box.

[0058] Step S3: Flocking operation steps.

[0059] The operator presses the foot switch 4. The control module receives the connection signal and immediately activates the high-voltage generator, applying high voltage to the flocking machine 2. At this time, the flocking fibers are ejected vertically downwards from the flocking outlet 31 under the influence of an electrostatic field. Simultaneously, the operator holds the workpiece steadily inside the control box 5, moving or rotating it at a uniform speed and smoothly according to the workpiece's surface shape, ensuring that all areas of the workpiece's surface to be flocked receive the flocking fibers ejected from the outlet 31 sequentially and evenly. During this process, the distance between the workpiece's surface to be flocked and the outlet 31 should be maintained within 3 to 5 centimeters, and the surface to be flocked should be kept as perpendicular as possible to the direction of the flocking fibers ejected from the outlet 31 to achieve the optimal flocking density and upright effect.

[0060] Step S4: Stop the extraction process.

[0061] Once the flocking density in the current area of ​​the workpiece reaches a satisfactory level, or when the flocking of the entire workpiece is complete, the operator releases the foot switch 4. The control module receives the disconnect signal and immediately performs two actions: first, it cuts off the power to the high-voltage generator module, stopping the flocking process; second, it activates the charge discharge circuit (if equipped) to quickly discharge any residual charge on the high-voltage path. After the high-voltage indicator light goes out (indicating that the high voltage has been completely shut off and discharged), the operator can safely remove the flocked workpiece from the operating box 5 and lay it flat to allow the adhesive to cure. If continuous operation is required, steps S2 to S4 can be repeated.

[0062] It should be noted that the control method in the embodiments of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.

[0063] The technical solution described in the above-mentioned embodiment of this application achieves a human-machine separation, foot-controlled start / stop, and in-box operation mode by fixing the high-pressure flocking machine 2 to the built-in main unit 1, the flocking outlet 31, and setting up an independent open operation box 5 controlled by a foot switch 4. This solution completely frees the operator's hands, allowing them to focus on moving the workpiece within the operation box 5 via the operation surface 51, thereby significantly improving operational safety, convenience, and consistency of flocking quality. Simultaneously, the open operation box 5 and automatic flocking recovery function effectively improve the working environment, while multiple safety designs such as grounding detection and automatic charge discharge construct a complete safety protection system, fundamentally overcoming the safety hazards and operational inconveniences of traditional handheld electrostatic flocking equipment.

[0064] Obviously, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
